One idea would be to have a self calibrating projector, a small sensor built into the projector body and software that just went through a self calibration routine.

Marantz did something like this with their front projector. It came with a tristimulus pod, optimized for their projector, that fit over the lens and followed an internal routine. The only down side to this was the fact that the screen's affect on the image could not be included in the measurements. They may have specified one or two screens to match their procedure, but I'm not familiar with all the details. Front projection is a two-piece display system and should be calibrated by taking the readings off of the screen.
Some medical monitors and professional graphics monitors come with a similar setup. The best displays I'm aware of for not even needing calibration are Joe Kane's Samsung projectors. They are the H710 and H800. Joe specifies the two screens he developed with Stewart to go with these devices. These projectors are set up from the factory to deliver accurate color space and grayscales for NTSC, PAL, and HD.
They also deliver CRT-like color performance. CRTs are still predominantly used for mastering video programs in the professional community. This may change over time but it'll be a long time coming. Phosphors cannot achieve HDTV's expanded colorspace. Joe's projectors are unique in that they offer the option of setting up the color space automatically for either NTSC or HDTV! Currently, the vast majority of HDTV programs are mastered for NTSC colorspace and when viewed on a display calibrated for HDTV colorspace skew the image away from that which was intended by the program producer.
